DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0016] Embodiment 1:

[0017] The present invention provides a pigment grinding device for art teaching, such as Figures 1 to 6 As shown, it comprises: a mounting frame 1, the number of the mounting frames 1 is set to two, a connecting column 2 is symmetrically and equidistantly mounted between the bottom ends of the inner walls of the two mounting frames 1, a driving rod 3 is symmetrically and rotatably connected to the top ends of the inner walls of the two mounting frames 1, a driving motor is installed inside the mounting frame 1, and the output shaft of the driving motor is connected to the driving rod 3 by a clamping connection; A grinding assembly 4 is rotatably connected between the two driving rods 3, and the grinding assembly 4 includes a grinding barrel 41 rotatably connected to the top of the driving rod 3, a blocking plate 42 is clamped and installed on the top of the inner wall of the grinding barrel 41, and a collecting box 46 is slidably connected to the bottom end of the inner wall of the grinding barrel 41, and a screen 47 is equidistantly embedded and installed inside the collecting box 46. A baffle 49 is rotatably connected to one end of the collecting box 46, and a convex ring 410 is welded on one end face of the baffle 49 close to the screen 47, and the convex ring 410 and the grinding barrel 41 are connected by threads. The screening holes of the screen 47 become larger from left to right, and are used to screen raw materials.

[0018] like Figure 3 and Figure 4 As shown, the inner wall of the grinding barrel 41 is symmetrically provided with positioning grooves 43, and an arc-shaped piece 44 located in the positioning groove 43 is welded to the inner wall of the grinding barrel 41, and a memory metal sheet 45 is attached to the outer side of the arc-shaped piece 44 and fixedly installed on one side of the collection box 46; When the memory metal sheet 45 and the arc-shaped piece 44 are fitted together, the memory metal sheet 45 is deformed. The deformation of the memory metal sheet 45 generates an extrusion force, which increases the friction resistance between the collection box 46 and the grinding barrel 41, thereby increasing the difficulty of disassembling the collection box 46 and the grinding barrel 41, thereby achieving the purpose of controlling the extraction depth of the collection box 46.

[0019] like Figure 3 and Figure 4 As shown, the baffle plate 42 and the collection box 46 are combined into a circle, the outer side of the collection box 46 and the inner wall of the grinding barrel 41 are attached to each other, and the baffle plate 42 and the inner wall of the collection box 46 are welded with arc strips 48, and the cross-sectional surface of the arc strips 48 is triangular; The combined circles prevent the pigments from interlacing, thereby blocking the pigments during grinding, and the curved strips 48 move the pigments to one end, so that pigments of different particle sizes are ground separately after grinding, thereby improving the grinding effect.

[0020] like Figure 3 and Figure 4 As shown, grinding balls 411 are arranged equidistantly inside the collecting box 46, and the grinding balls 411 are separated by screens 47; As the collecting box 46 rotates, the grinding balls 411 are driven to rotate, and the grinding balls 411 are moved and fall downward due to gravity. When the grinding balls 411 fall, they strike and grind the raw materials of the pigment, and the grinding effect of the pigment is improved by the separated grinding balls 411.

[0021] like Figure 3 and Figure 4As shown, a filter screen 412 is embedded and installed at the bottom of the inner wall of the collection box 46, and an extrusion strip 413 is installed at the top of the filter screen 412. A screw runs through the extrusion strip 413, and the screw passes through the filter screen 412 and the collection box 46 and is connected by threads; The filter screen 412 can be easily installed, the installation difficulty of the filter screen 412 is changed, and the filter screen 412 can be easily disassembled and replaced.

[0022] like Figure 6 As shown, an adjustment assembly 5 is installed on one end face of one mounting frame 1, and the adjustment assembly 5 includes a fixing block 51 fixedly installed on one end face of the mounting frame 1, and columns 52 are symmetrically welded on the top of the fixing block 51, and the outer sides of the two columns 52 are sleeved with the same positioning frame 53; The positioning frame 53 is moved. When the positioning frame 53 moves, it moves along the outer side of the column 52 to prevent the position of the positioning frame 53 from being offset after it moves, so that it moves up and down along a vertical line with the ground.

[0023] like Figure 6 As shown, the top of the fixed block 51 is symmetrically and movably connected with a vertical plate 54, and a triangular groove is equidistantly provided on one end surface of the positioning frame 53 close to the vertical plate 54. A rotating column 57 is rotatably connected inside the vertical plate 54, and a rotating plate 56 is welded to the middle of the outer surface of the rotating column 57. A torsion spring 58 is installed between the edge of the outer surface of the rotating column 57 and the vertical plate 54. A rectangular groove is provided inside the vertical plate 54, and the rotating plate 56 is located inside the rectangular groove. When the positioning frame 53 moves upward, the positioning frame 53 drives the rotating plate 56 to rotate, and the rotating plate 56 enters the rectangular groove for placement. At the same time, when the rotating plate 56 rotates, it drives the rotating column 57 to rotate, and when the rotating column 57 rotates, it drives the torsion spring 58 to twist. The restoring force of the torsion spring 58 is used to reset the rotating plate 56. After the rotating plate 56 is reset, it enters the triangular groove of the positioning frame 53, so that the positioning frame 53 cannot move downward, thereby positioning the movable positioning frame 53.

[0024] like Figure 6 As shown, a slider 55 is welded to the bottom of the vertical plate 54 and the slider 55 is slidably connected to the inside of the fixed block 51. The two sliders 55 are internally connected to the same bidirectional threaded rod 59 through threads, and the bidirectional threaded rod 59 is rotatably connected to the inside of the fixed block 51. By rotating the bidirectional threaded rod 59 , the bidirectional threaded rod 59 drives the two sliders 55 to move relative to or away from each other. When the two bidirectional threaded rods 59 move relative to or away from each other, they drive the vertical plates 54 to move, so that the two vertical plates 54 move closer to or farther from each other.

[0025] like Figure 1 and Figure 2As shown, a positioning rod 6 is rotatably connected inside the vertical plate 54, and both ends of the positioning rod 6 are respectively in contact with the inner wall of the mounting frame 1, and a plurality of barrier strips are slidably connected between the outer sides of the two positioning rods 6; The positioning rod 6 can protect the outer side of the grinding barrel 41 to prevent the grinding barrel 41 from being separated from the device when rotating, and separate the two adjacent grinding barrels 41 through the action of the barrier strip to prevent the two grinding barrels 41 from colliding with each other.

[0026] Working principle: In the actual process of the device, the personnel put the pigment raw material into the innermost space of the collection box 46, and then place the grinding ball 411 between each screen 47 in turn, and then the personnel put the collection box 46 into the grinding barrel 41. At this time, the arc-shaped member 44 and the memory metal sheet 45 are fitted, and then the personnel rotate the baffle 49, and the baffle 49 drives the convex ring 410 to enter the grinding barrel 41, and at this time, the arc-shaped member 44 and the memory metal sheet 45 are clamped and fixed; Then the personnel put the grinding barrel 41 between the two rotating driving rods 3, and then the personnel move the positioning frame 53. When the positioning frame 53 moves, it moves along the outer side of the column 52. When the positioning frame 53 moves upward, the positioning frame 53 drives the rotating plate 56 to rotate, and the rotating plate 56 enters the rectangular groove for placement. At the same time, when the rotating plate 56 rotates, the rotating column 57 is driven to rotate, and when the rotating column 57 rotates, the torsion spring 58 is twisted, and the resetting force of the torsion spring 58 is used to reset the rotating plate 56. After that, it enters into the triangular groove of the positioning frame 53, so that the positioning frame 53 cannot move downward, and then the movable positioning frame 53 is positioned. When the positioning frame 53 moves, it drives the positioning rod 6 to move, so that the positioning rod 6 fits with the outer side of the grinding barrel 41, preventing the grinding barrel 41 from falling along the outer side of the driving rod 3 when rotating, ensuring the stability and safety of the grinding barrel 41. At the same time, the positioning mechanism is adjusted according to the size of the grinding barrel 41, so that the design has high flexibility and applicability, and can cope with grinding barrels 41 of different specifications; When disassembly is required, the two-way threaded rod 59 is rotated, and the two-way threaded rod 59 drives the two sliders 55 to move relative to each other. When the two-way threaded rods 59 move relative to each other, the vertical plate 54 is driven to move, so that the two vertical plates 54 are close to each other, so that the rotating plate 56 is separated from the positioning frame 53, and then the positioning frame 53 is lowered by gravity, which can facilitate the resetting of the positioning frame 53 and reduce the difficulty of resetting the positioning frame 53, so that it is convenient for the positioning frame 53 to enter the outside of the grinding barrel 41 when it is used next time, further reducing the difficulty of positioning the grinding barrel 41; Finally, the driving rod 3 drives the grinding barrel 41 to rotate, and at this time, the grinding barrel 41 drives the collecting box 46, and when the collecting box 46 rotates, the grinding balls 411 are driven to rotate, and the grinding balls 411 are moved, and fall downward due to gravity. When the grinding balls 411 fall, they knock and grind the pigment raw materials, and then the raw materials with finer particles after grinding enter between the two screens 47 along the screen 47 under the action of the arc strip 48 for grinding. At this time, the raw materials ground between the two screens 47 enter the second screen 47 under the action of the arc strip 48. At one end, different particle sizes of raw materials are ground separately according to the number of screens 47. By setting screens 47 with different apertures, the size of pigment particles can be accurately controlled to ensure that the final pigment has a more ideal particle size distribution to meet the use requirements. Compared with the single grinding ball 411 method, the use of such multi-layer screens 47 and grinding balls 411 can disperse and reduce the concentrated collision of grinding balls 411 in a unit volume, thereby reducing the wear on the inner wall of the grinding barrel 41 and the grinding balls 411 themselves, and extending the service life of the equipment; Finally, the baffle 49 is disassembled, and the convex ring 410 and the grinding barrel 41 are separated. Then the collecting box 46 is pulled, and the opening direction of the collecting box 46 is observed. When the opening direction of the collecting box 46 is perpendicular to the ground, the collecting box 46 is pulled, and the finest raw materials inside the collecting box 46 are screened along the filter 412. Then the personnel collect the screened raw materials, which changes the method of the prior art that requires carrying the screening device again. This method can facilitate the grinding of the raw materials and can screen the ground raw materials. One machine has multiple uses, which reduces the equipment that personnel need to carry, thereby reducing the labor intensity of the operators.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
